Question

我想获得在线主管的项目名称和描述

我的主管控制员：

public ActionResult SupervisorDashboard()
{
    var message = TempData["message"] as string;
    var name = (from s in dc.Supervisors
            where s.sup_email == message
            select s.sup_fname).SingleOrDefault();
    ViewBag.username = name;
    return View();
}

public ActionResult ViewProject()
{
    var message = TempData["message"] as string;
    var name = (from s in dc.Supervisors
                where s.sup_email == message
                select s.sup_fname).SingleOrDefault();
    ViewBag.username = name;

    var supid= (from s in dc.Supervisors
                 where s.sup_email==message
                 select s.sup_ID).SingleOrDefault();

    var projectdata = (from s in dc.OfferedProjects
                    where s.FK_sup_ID==supid
                        select s);
    return View(projectdata);
}

我的主管模特：

public class SupervisorModel
{
    public Supervisor supervisor { get; set; }
    public OfferedProject offerproject { get; set; }
}

我的观点：

@model IEnumerable<FYPManagment.Models.SupervisorModel>
@using FYPManagment;
@{
    List<OfferedProject> projectdata = (List<OfferedProject>)ViewData["projectdata"];
    ViewBag.Title = "ViewProject";
    Layout = "~/Views/Shared/_SupervisorDashboarLayout.cshtml";
}

@foreach (var item in Model)
{
    <tr>
    <td>@item.offerproject.proj_title</td>
    <td>@item.offerproject.proj_description</td>
    <td>
    <a href="#">Send Request</a>
    </td>

    </tr>
}

我的家庭控制器：

TempData["message"] = email;
//Session["user"] = email;
if (type == "supervisor")
{
    return RedirectToAction("SupervisorDashboard", "Supervisor");
}

我的Supervisor Dashboard操作正在获取在线用户的电子邮件，但查看项目操作中的相同代码无效。我将非常感谢你宝贵的时间。

Answer 1

您只能在TempData ONE TIME中读取密钥的值（因此名称为＆＃39; temp＆＃39;）。它一旦被读取就被删除。将TempData的使用更改为ViewBag或会话，它将起作用。

Asp .net mvc session
